DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention provides various vehicle information, such as vehicle information such as vehicle speed and engine speed, in various display patterns on corresponding display units on the display surface. The present invention relates to a display device for a vehicle.

<Prior Art> As a vehicle display device of this type, for example, those shown in FIGS. 5 and 6 are known. (Actual exploitation 57-
The electronic display type meter 1 as a vehicle display device is arranged in a meter hood of an instrument panel (not shown), and various vehicle information is a numeral. , A symbol, a symbolized symbol, or a bar graph display, and various display patterns are displayed on the driving vehicle via the corresponding display units 3 on the display surface 2. As the display unit 3 in the illustrated case, a speedometer display unit 4 corresponding to the vehicle speed, a tachometer display unit 5 corresponding to the engine speed, a fuel gauge display unit 6 corresponding to the remaining amount of fuel,
A water thermometer display portion 7 corresponding to the cooling water temperature is shown.
Then, on the substrate 8 arranged on the back surface side of the display surface 2, the fluorescent display tubes 9 are provided at positions corresponding to the respective display portions 4, 5, 6, 7.
Specifically, a speedometer fluorescent display tube 10, a tachometer fluorescent display tube 11, a fuel gauge fluorescent display tube 12, and a water temperature gauge fluorescent display tube 13 are attached. These fluorescent display tubes 10, 1
Reference numerals 1, 12, and 13 are connected to a sensor, a control device, a power source, and the like (not shown) to be operated.

<Problems to be Solved by the Invention> However, in such a conventional vehicle display device, in order to further improve the visibility, for example, a display pattern displayed on the tachometer display unit 5 in FIG. When it is attempted to form an arch, the size L1 of the fluorescent display tube for tachometer 11 itself shown in FIG. 6 has to be increased to the size L2 shown in FIG. 7, and thus the cost is increased accordingly. There was room for improvement in that layout in a limited space would be difficult.

In particular, a bar-shaped display unit such as the tachometer display unit 5 is arranged above the display unit such as the speedometer display unit 4 such as a numeral so as to be curved in an arch shape. The part is above the display part such as numbers, as if it were "rainbow"
An excellent design of a display device that is laid out in such a manner is known. However, in order to obtain such an excellent design, not only is the bar graph display curved in an arch shape, but further Since this bar graph itself has to be enlarged to some extent, the size L2 of the tachometer fluorescent display tube 11 is further increased, which is not preferable.

This invention was made by paying attention to such a conventional technique, and without increasing the size of the fluorescent display tube, the bar graph display is curved / enlarged into a large arch shape to display characters and numbers. A display device for a vehicle that can be arranged on the upper side is provided.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the vehicle display device according to the present invention displays various vehicle information on the corresponding display portions on the display surface arranged in the front part of the occupant. In a vehicular display device displaying various display patterns, the display surface is arranged in a substantially horizontal upward state to form a first display surface, and the display surface is inclined rearward above the first display surface. Arranged and said first
A concave mirror that is curved in both the up-down direction and the left-right direction is provided as the second display surface in order to reflect and magnify the display surface, and a number or character is mainly displayed on the display unit of the first display surface. The display unit is arranged on the front side of the first display surface and in the left-right center portion so as to be close to the left-right center portion of the second display surface, and another display unit for displaying a bar graph along the left-right direction is displayed. It is arranged on the rear side of the first display surface and separated from the second display surface.

<Operation> Even if the other display portion based on the bar graph of the first display surface, which is the original, is linear and has a small size, by reflecting and enlarging it on a concave mirror as the second display surface,
The bar graph display is curved and enlarged into a large arch.

Further, of the first display surface, the main display portion on which numbers and characters are displayed is arranged in the vicinity of the left and right central portions of the concave mirror, and the other display portion on which the bar graph is displayed is arranged apart from the concave mirror. While the other display part is laid out like a rainbow on the upper side of the main display part, it has an excellent design,
Distortion due to the concave mirror of the main display is suppressed to a minimum.

<Embodiment> A preferred embodiment of the present invention will be described below with reference to FIGS. In the following description, the same parts as those of the conventional one will be denoted by the same reference numerals, and overlapping description will be omitted.

A plurality of display units 16 are provided on the first display surface 15 on the fluorescent display tube 14, and various display patterns representing various vehicle information are displayed on each display unit 16. Among these various display patterns, a display pattern in which numbers and characters are displayed will be referred to as a "main display unit", and a display pattern in which a bar graph is displayed will be referred to as "another display unit". In this embodiment, the speedometer display unit 20 is the "main display unit" and the tachometer display unit 21 is the "other display unit".

The first display surface 15 including the speedometer display unit (main display unit) 20 and the tachometer display unit (other display unit) 21 is in a substantially horizontal upward state, and the speedometer display unit 20 is It is arranged on the front side of the first display surface 15 and on the left and right central portions, and the tachometer display portion 21 is arranged on the rear side of the first display surface 15.

In front of and above the first display surface 15, a concave mirror 17 arranged in a rearwardly inclined state is provided in combination, and the mirror surface of the concave mirror 17 is the second display surface 18. The concave mirror 17 is used for the display unit 1 of the first display surface 15.
In order to reflect and magnify 6 to project it, the image is curved in both the vertical direction (X direction in the drawing) and the horizontal direction (Y direction in the drawing). For example, when a certain pattern is reflected and magnified by the concave mirror 17, as shown in FIG. 4, a pattern at a position far from the concave mirror 17 is greatly magnified and distorted into a curved shape, but a pattern at a close position is The distortion is small. Therefore, in this embodiment, as described above, the speedometer display unit (main display unit) 20 for displaying numbers is “closely arranged” with respect to the concave mirror 17 and the tachometer display unit for displaying a bar graph (other display). 21) is “spaced apart” from the concave mirror 17. That is, on the optical path 22 from the display unit 16 to the eyes 19 of the driver, the distance between the display unit 16 and the reflection point 23 where the light emitted from the display unit 16 is reflected on the concave mirror 17 is calculated from the speedometer display unit 20. The distance D1 of the emitted light is arranged to be closer to the distance D2 of the tachometer display unit 21.

Therefore, even if the tachometer display portion 21 based on the bar graph on the original first display surface 15 has a linear shape and a small size, it is reflected and magnified by the concave mirror 17 serving as the second display surface 18 and projected. The tachometer display portion 21 is curved and enlarged in an arch shape. On the other hand, of the first display surface 15, the speedometer display portion 20 for displaying numbers is arranged close to the concave mirror 17, so that the tachometer display portion 21 is located above the speedometer display portion 20 as if it were a rainbow. A layout laid out like this is obtained. Further, the speedometer display unit 20
Are arranged in the vicinity of the left and right central portions of the concave mirror 17, so that the distortion of the speedometer display unit 20 is suppressed to a minimum,
There is no problem in reading the speedometer display section 20.

When the first display surface 15 is reflected by the concave mirror 17 and projected, the driver can see the image 24 of the first display surface shown on the second display surface 18 of the concave mirror 17 behind the concave mirror 17 (arrow Z). Direction), that is, it looks as if the image were formed at a distant position from the driver, so that various reflected display patterns can be visually recognized without significantly moving the line of sight.

Further, of the display units 16 of the first display surface 15, the “main display unit”
Display unit 20 displaying the display pattern as
Is arranged closer to the concave mirror 17 than "the other display portion", and therefore, the distortion due to the concave mirror is reflected and enlarged while being reflected to the minimum.

Although various display patterns are displayed using the fluorescent display tube in the above embodiment, other light emitting elements such as liquid crystal and light emitting diode may be used instead of the fluorescent display tube.

<Effect of Device> Since the vehicular display device according to the present invention is as described above, it is possible to bend / enlarge the bar graph display into a large arch shape without enlarging the fluorescent display tube to display characters or numbers. Since it can be arranged on the upper side of the display and the fluorescent display tube does not have to be upsized, it has an effect of facilitating the layout in a limited space.

And, in particular, the display pattern of the main display portion, which is closely related to the safe running of the vehicle, can be shown in a state in which the degree of distortion is suppressed to a small level, and the concave mirror is used as the second display surface to reflect and project it. The image formation position of the reflected display pattern is farther from the driver, and there is an effect that the driver's visibility is further improved because there is no need to greatly move the line of sight.
